Patient: Ultrasound findings on October 12, 2009: Both thyroid glands are homogeneous in parenchymal echogenicity. 2 hypoechoic nodules with unclear borders are visible in the left lobe of the thyroid gland, the largest is located in the upper part, with a size of about 0.8*0.5cm, and the central nodule is about 0.6*0.4cm, with a comet’s tail sign inside. A hypoechoic nodule was seen in the right lobe of the thyroid gland, with a size of about 0.5*0.4 cm and a clear border. No enlarged lymph nodes were detected in both necks. After returning to Ordos, another nail function was done and the results were within the reference values. Now the situation is that the nodules are less than 1CM, and the ultrasound has some suspicion that the nodules are cancerous, what should I do? Ultrasound-guided puncture can be done. Patient: The pathological results of ultrasound-guided puncture of three tissues have been released, and the diagnosis is nodular goiter. I am very thankful that my depressed mood for a period of time has been cleared up. We will review the ultrasound and thyroid function tests once every six months or so, and compare the results with the last test to make a better judgment.
